I was at Pocono-CSD memorial day w plenty ofther Z's
I was running my race car but I took my Z out and I was very impressed w her
on street tires w coil overs and 550hp I was able to BLOW away a Viper competition coupe and a 360 Challenge race car, I think they were both pretty surprised

They were probably not great drivers though
unforetunately my alternator died & my oil temp got up to 265
so she was flat bedded home
For next time I am adding an oil cooler, new wheels w much better rubber, harnesses, and some new seats, maybe OMPs or Caravaggios
